         1. Two Sum

            Given an array of integers, return indices of the two numbers such that they add up to a specific target.

You may assume that each input would have exactly one solution.

Example:

Given nums = [2, 7, 11, 15], target = 9,

Because nums[0] + nums[1] = 2 + 7 = 9,
return [0, 1].

             */
        public int[] TwoSum(int[] nums, int target)
        {
            for (int i = 0; i < nums.Length; i++)
            {
                for (int j = i + 1; j < nums.Length; j++)
                {
                    if (nums[i] + nums[j] == target)
                        return new int[] { i, j };
                }
            }
            return new int[0];
        }
    }
}
